The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..

With this essay we have had the intention of observing Linköping University as an example of a public authority undergoing change. In the information society of today, the increasing competition and internationalization affects, not only companies and organizations, but also the public sector. After having been concerned with neutral information spread only, according to"the third mandate", employees at the Department of Information at Linköping University has also started dealing with marketing, so as to increase the recruitment of students. As a result of this, the work team has been divided into an editorial staff and a department with emphasis on market issues. To strengthen the trademark of Linköping University one has chosen to mediate certain values representative for the university - an interdisciplinary and innovative approach and an entrepreneurial spirit.

The purpose of this essay is to examine Egyptian university students´attitudes about the Egyptian education system´s ability to support a democratic process in Egypt. In order to carry out my study, scientific books and articles have been read and interviews have been made among Egyptian university students. The interviews contained questions about the Egyptian education system´s impact on the democratic process in Egypt and which impact the Egyptian education system has had on the Egyptian revolution.The conclusion drawn from my study is that Egyptian university students find the contemporary Egyptian education system based on authoritarian rules and with a lack of democratic values. The Egyptian university students believe that to establish democratic institutions in Egypt, the Egyptian citizens need a better understanding about democratic values. However, some of the students believe that the democracy that should be established in Egypt, must be based on Islamic values and to succeed with that, Islamic studies must play a greater part in the Egyptian education.When it comes to the Egyptian education system´s impact on the Egyptian revolution the Egyptian university students´opinions were somehow divided. .

A variety of demands have to be considered in the design of a new opera house in Galärvarvet. All possible viewpoints are important to be aware of, as is the need for the new building to be a contrast to the already existing opera house in Stockholm. The restricted site also makes a multitude of demands on the building's design.By rationalizing the layout and structure and also by making the footprint smaller, the complex building of over 30 000 square meters can be fitted and blended into the existing physical context. Unlike the existing opera house in Stockholm, the new opera house shows the rationality and the advanced technology that lies behind the scenes and becomes the character of the entire building. Through the dynamic façade, the new opera can convey any character it so desires, just like scenes do through different settings.

There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

This thesis concerns how Sweden relates to life cycle assessment (LCA) in the construction process. LCA means analyzing a products impact and the analysis includes the whole life span of the product. A building has a high complexity and the combination with its unique shape will make the LCA more comprehensive, unlike e.g. aluminum cans. Recently there has been a development of a working procedure in the construction industry.

This diploma work addresses the question of how much energy is spent whenmanufacturing the components of a building as well as of how much energy is used inthe production of a building. The object of the studies is BioCentrum at the SwedishUniversity of Agricultural Sciences in Ultuna just outside the city of Uppsala. The aimof the work was to investigate how much energy was consumed when manufacturingand production in relation to the management, how many years the production wasrepresented. It was also a study in how mature the construction industry is to answerhow much energy was consumed in manufacturing.In order to get these answers a question form was developed and sent to thesuppliers to BioCentrum. In this form they were to respond to the quantity suppliedto BioCentrum and the amount of energy was spent when manufacturing thecomponents.

AbstractThe indoor environment affects the human performance. Noise pollution, poor lightning and coloring are some of the factors that affect our work performance. The human is also affected by the air change and temperature, these factors are in most buildings possible to adjust and through this make economic savings. To find out about the indoor environment in the O-building a questionnaire was handed out, measurements/surveys and an interview was also made. 108 questionnaires where handed out to employees and students.

The hotel is located on Skatholmen in the archipelago of Stockholm, Värmdö county. The hotel building has an open structure characterized by hospitality and the nature outside. The rooms have stunning views of the island landscape and lush forest. With biodiversity and valuable nature in mind, the building has been designed with a structure that should not be too intrusive in the surrounding landscape. The building is meant to blend into the dark silhouette of the island and to give a light footprint on the topography of the landscape.The use of well-chosen materials and similar design, both in plan and facade, creates a consistent building despite the building's somewhat playful expression.

This is a project showing a proposal on how a high-rise building gains qualities similar to middle rise houses of 7-9 stories. The closed, isolated and often anonymous life in the high building opens up through gardens. The resident meet the outdoor environment on the balcony, or has direct access to a garden.Instead of moving in a closed core, the resident will meet the climate and outdoor conditions as soon as he or she leaves the apartment.The project consists of two parts, where the first is presenting a building proposal, the second is expanding the knowledge through background research. The topics are history concerning the skyscraper and the skyscraper globally, closing up with the situation in China..

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.
